Artificial tree



FIG. 1 is a front perspective view of an artificial tree showing my new design, the rear and sides being identical;

FIG. 2 is a front perspective view of a second embodiment of FIG. 1, the rear being identical; and,

FIG. 3 is a side elevational view of FIG. 2, the opposite side being identical. 

I claim the ornamental design for an artificial tree, as shown and described.
